New GPS technology: GLONASS

There is a "new" GPS technology to increase accuracy when standing inside cities. The idea is simple, increase the number of satellites that your phone receive, so then you'd have strong signal and therefore a more accurate position.

This video explains it very well.

What SVN hosting is better?

Since there are plenty of alternatives of free SVN hostings, I made this post to know which are the best. All of this alternatives are free.


Google code [code.google.com]


Its a easy to use, with google account integration that make it an easy way to start with SVN. It also provides a wiki integrated with the SVN repository that could be helpful to document open source projects and make them easy to share. A tool for code comparing between versions is available!



Better Codes [bettercodes.org]

It has a very heavy website, with very useful tools to handle a project. It's the best alternative if you want your project to be private. I know that sharing is good, but sometimes you need your projects to be private.



Assembla [assembla.com]


One great thing about Assembla is the email notification about commits. Each time a commit is done, all the team is going to be forwarded with the change-set and the details of the commit. It'd be annoying for some people, but for small projects it's cool stuff because it helps with communication.



I'll be increasing this list with more alternatives as long as I get the chance to discover other good SVN Hostings. If you know a hosting that doesn't appear in the list, then leave your comment in the section below and I'll add it!

Unit Tests: automatically generating

I've recently assisted to a course about different ways to automate testing. It includes generating, coverage and generating input for the tests.

CodeCover

This is a tool that analyses the code coverage of tests. When we write tests, the idea is that all the lines of our code will be executed. This tool allows us to check it. The result is going to be shown directly over the code with helpful color highlighting.
An Eclipse plugin is available and also a standalone version for use from Command Line and Ant.
Link to CodeCover: http://codecover.org/index.html

Randoop

This is my favorite one. It randomly generates unit tests! The best thing of this is that is really useful, you don't need to write any single line of test code.

How it works? For each method tries to generate code to call the method in different ways, and using different seeds of code generates random code to achieve unexpected exceptions or problems with the class invariant. To check the class invariant it requires a method usually called repOk(). This method ensures that the object under test is in a valid state. For example:

@CheckRep
public boolean repOk() {
    if (size < 0 ) return false;
    if (size == 0 && last != null) return false;
    return true;
}


Other example a little bit more complex:

@CheckRep
public boolean repOK() {
    int itemsLeft = size;
    Node current = last;
    while (
itemsLeft>0 && current!=null) {
        current = current.next;
        
itemsLeft--;
    }
    return (
itemsLeft==0 && current==null);
}

Eclipse plugin http://randoop.googlecode.com/hg/plugin/doc/index.html


Jumble

Given a class and a test case, this tools mutate(ie changes) aritmetic operands and logic. The it runs the tests, and if they won't fail, then you've bad test cases.
It's very easy to use and more than helpful.

jumble http://jumble.sourceforge.net/

Korat

Korat helps you to create input data for testing. Given a class invariant and domain restriction about its attributes, Korat generates valid structures and with no redundant results.
This is very usefull if you have a complex data type and you want to test it with lots of valid data sets.




Pex

A powerful tool that uses constraint solving engine to execute all your code and detect possible fails. It's only available for .NET.
There is a fun online app which is called Pex for fun that makes you guess code by modified constraint solving engine.

Kindle 4 get oxidized



Part 1:
The problem

I bought a Kindle 4 five months ago. Since then I've protecting my gadget using a cover that I've bought via focalprice. I'm so proud of my Kindle since is quite cheap, and reading books inhere is a pleasure. One day I get my Kindle out of the cover and realized that the back part of the kindle was dirty, with black spots. Doing a little of research I get to know that if you leave your Kindle inside some kind of covers I could get all oxidized.
Also my girlfriend and a friend of mine run in the same problem.

Part 2:
What Amazon said

I've send an email to amazon to complain about my defective Kindle 4. I didn't get an answer at all because I got an automatically email response. I'll be calling amazon in a couple of days and then I'm gonna update my post.

Part 3:
Solution

Unknown yet.

Files on the Cloud: the best of the best

Hi there! I've been doing a little bit of research about which online file sharing is the best, and I got to the following conclusions:


Google Drive

Pros: 5GB free. Very cheap pricing: $2.5/month for 25GB and $5/month for 100GB. The integration with google docs its an advantage.
Cons: no linux support yet.


Dropbox

    Pros: 2GB free, up to 23GB free doing referral and camera upload(easy to achieve). Supports all platforms and smartphones. Very easy to use and to share files.
    Cons: Pricing starts at $10/month for 100GB.


    GlideOS


      Pros: 30GB free! It's a complete OS online. You can customize it and runs directly from a browser. Allows you to edit files online: doc, xls, jpg and more.
      Cons: no mobile app.

      For a complete review about Google Drive, Dropbox, SkyDrive, SugarSync, iCloud and others check this link. But be aware, it's a little bit outdated.

        Hello world!

        This is me coming out of the box bucket!




        I'm a 22 years old software engineering student trying to get in touch with this old-fashion trendy blogging habit. Golf and playing drums were my habits, but now I'm a world traveler fanatic!

        I love technology, and I also like being in touch with the latest news about this new gadget or that software that have just been released!
